ATTORNEY Patented Sept. 3, 1940 UNITED STATES PATENT OFFICE 10 Claims. (:1. z s sa I My invention relates to foldable bag supporting devices or hangers for a new type of hot water syringe bag now appearing on the market and having a wide mouth or upper end portion which is attached to the device.

The purpose of the invention is to provide a simple yet durable support which when in use may be supported on a hook and when not in; use can be folded up and packed away in a suit-;

able compartment for future use.

A further object of the invention is to provide a simple and durable form of a collapsible frame comprising but three cooperating metal parts suitably joined together to permit the 18 members to which the bag is attached to be moved with respect to the hanger member so that the bag may be readily folded while still supported in the frame, further to provide a bag supporting device which can be unfolded and attached to a hook on the wall in a way to allow the bag to be suspended and opened preparatory tofilling with water.

With these and other objects in. view the invention resides and consists in the construction,

5 of a frame formed of a few sheet metal and wire parts as illustrated, in the accompanying draw-. ings, forming a part of this specification wherein similar characters of reference will be found to designate like or corresponding parts throughout the several figures, and of which,

Fig. 1 shows a perspective view of my improved bag supporting device having the upper portion of a bag attached and supported thereby in an open position.

Fig. 2 is a further perspective view of my improved device in a closed position, having a bag attached and also in a collapsed or closed position.

Fig. 3 shows a central vertical cross section through the device and bag illustrated in Fig. 1, the bag being broken away, better to illustrate the supporting loop of the wire member of the frame.

Fi 4 is a perspective view of the device, the

back being partially broken away and the wire frame member being extended and disconnected, showing the hanger irrespective of the bag.

Fig. 5 shows a perspective view of a modified form of the device having the upper portion of a bag in an open position, secured thereto and the lower portion broken away, the device being formed principally of wire and operates similar to the form shown in the preceding figures.

Fig. 6 shows the wire form of the invention with bag attached, both folded, forming an illustration comparable with that of Fig. 2, and' Fig. 7 shows-"a perspective view of a portion of the bag supporting device, somewhat like the illustration of Fig. 4. v Referring in detail to the characters of refer-. ence marked upon the drawings, It represents a backof the-bag supporting device having an openingi'l l in its upper end portion to permit it tobe hung on a supporting hook, not shown.

l2 represents a rectangular shaped wire frame, 10;;

the rear cross member of which is hingedly connected to the lower end of the backl. The aligned forward end portions or stubs l3-l3 of the wire frame are disposed inward in spaced relation to receive an attachable piece of light 15 metal tubing M. The forward top edge portion i5 of the rubber bag 16 in this instance is vul-, camzed to this tubing while the rear top edge portion l'lof the bag is similarly attached to the flattened piece of tubing l8 slidably mounted .291

on the back In beforementioned. In operating position the hinged wire frame member I2 is supported in a horizontal position, see Figs. 1, 3 and 4, by reason of an offset or loop l9 formed in its rear cross member. 20 between the two 2Q,

knuckles 2| of the supporting hinge and engaging against the back of the lower portion of the sheet metal back l0, see Fig. 3. The opposite end portions of the rear cross hinge member 20 of the rectangular wire frame 8i); l2 are offset upwardly as at 22, see Fig. 4, which serve to dispose the main supporting part of the frame I2 and tubing M on a. plane common with the upper end of the flattened piece,

of tubing [8 and thus supporting the open end 35;

of the water bag IS in substantially a horizontal position, see Fig. 2. It is obviously unnecessary to offset the wire frame 12 in the modified wire form of .the invention because the rear wire supporting bar. l8 and the tubing 14 are substantially on the same plane when the frame is in an open position. To close the bag, as shown in Fig. 2, and collapse the unit, the flattened piece of tubing l8,

together withits attached rear edge portion of the bag, is slid upwardly on the back which causes the wire frame to swing on its hinge and fold against the back and collapse the water bag in the manner illustrated in Fig. 2. From this position it is a simple matter to fold the 50 ed, the frame I2 carrying the tubular member l4 across its front end portion and to which the upper front edge portion l5 of the bag is vulcanized. This rectangular wire frame, like that shown in the previous figures, includes an ofiset loop [9 formed in the rear cross member 20 between the supporting knuckles. 2| of the back to engage the cross bar l8 slidably mounted on the back frame Illa and whereby the bag supporting frame is retained in a forwardly distended horizontal position. It will further be apparent that when the bag is empty the operation of this frame would be substantially the same as that before described to the effect that when the cross bar [8 is manually slid upward on the back frame, causing the Wire frame to pivotiand fold against the back and collapse the hot water bag, the bag together with its supporting frame is drawn up into the folded position shown. in Fig. 6.

. Having thus described my invention, what I claim and desire to secure by Letters Patent is:

:1. A water bag supporting device comprising a back, a rectangular wire frame hingedly connected to the back, a movable bar slidable on said back, a bag supported from the frame and the movable bar, means intermediate the rear cross member of said rectangular frame adapted to engage said back andsupport the frame in an eX- tended horizontal position, said bar adapted to be slipped upwardly toward the top portion of said backlcausing the frame to pivot about its hinge and collapse the bag against the front face of isaid back.

2. A water bag supporting device comprising a. back, a. bar movably mounted on the back, a rectangular frame upon which a roller is mounted, a'water bag secured to the bar and roller,

'said frame being hingedly connected to the back so as to. allow its forward roller to be raised against the back, and. means to support said frame in an extended horizontalposition.

3. A bag supporting device for a water bag comtprising aback, a. bar slidably mounted thereon for vertical movement, a rectangular frame hingedly supported to the base of the back, means for supporting the frame in a horizontally extended position, said frame adapted to swing upon its hinge bythe raising of the front member of the extended portio in a manner to cause an attached bag to be folded against the back.

4:. A water bag supporting device comprising a back, abar movably mounted on the back, a

;.rectangular frame including a front cross mem extended position, a bag supported from said bar and the front cross member of said frame, said bag adapted to be collapsed by sliding the bar upwardly on said back and cause said frame to pivot on its hinge and swing against said back.

6. A water bag supporting device comprising a back, a bar slidably mounted thereon, arectangular frame hingedly connected to the back and including a front and rear hinged member and having a loop formed'in the rear hinged member of the frame that extends at a right angle to the side members of the frame, said loop serving to engage the back and support the wire frame in a horizontally extended position, so that a bag may be hung therefrom when secured to the slidable bar and the front member of the frame.
